Add a pkg_warn() function that emerge can then call to display warning
information during an emerge -pv <package>
The warning would be used to print out upgrade path information along with known
problems with the package. This is useful prior to installation so that an
administrator can have knowledge of difficulties prior to installation and
prepare for them.
This is planned for CVS ( per Jason ). Not sure if patching against current cvs
would be at all useful, or to wait until more of the new code is done ( ie is
doebuild being gutted? I thought so... ).
Still talking. Brian has already brought up issues with it.
(It won't be forgotten about without a bug either)
Talked about on gentoo-portage, encouraging decent changelog use and using
current -l feature to give output.
